Accordingly it can provide the excitement of PC gaming and browsing right on your TV’s large screen while matching the essential features of the popular game consoles. Basically, what you only need with … [Read more...]

DDR4 SDRAM which means in computing world for Double Data Rate Fourth Generation Synchronous Dynamic Random-Access Memory was released for public purchase during the second quarter of 2014. It is the higher version of the DDR3 but with a lesser voltage requirement of only 1.2 volts. Compared to … [Read more...]

DDR3 SDRAM which stands for Double Data Rate Type Three Synchronous Dynamic Random-Access Memory is the higher version of DDR2 and predecessor of DDR4. Compared to DDR2, it is faster and has the power to transfer data eight times of the internal memory speed that makes for a higher bandwidth … [Read more...]

Historically, while much more cost effective than SRAM per Megabit, traditional DRAM has always suffered speed and latency penalties making it unsuitable for some applications. Consequently, product manufacturers have often been forced to opt … [Read more...]

Conventional DRAM architectures have reached their practical upper limit in operating frequency and bus width. With mass market CPUs operating at over 300MHz and media processors executing more than 2 GOPs, it is clear that their external … [Read more...]

Memory chips are generally packaged into small plastic or ceramic dual inline packages (DIPs) which are themselves assembled into a memory module. The single inline memory module or SIMM is a small circuit board designed to accommodate … [Read more...]

By the end of the millennium, as memory subsystems standardised around an 8-byte data interface, the Dual In-line Memory Module (DIMM) had replaced the SIMM as the module standard for the PC industry. DIMMs have 168 … [Read more...]

With the introduction of Direct RDRAM (DRDRAM) in 1999 came the RIMM module (the name is not an acronym, but a trademark of Rambus Inc.). RIMM connectors have a form factor similar to DIMMs and fit within the same board area … [Read more...]

When a computer system boots up, it must detect the configuration of the memory modules in order to run properly. For a number of years, Parallel Presence Detect (PPD) was the traditional method of relaying the required information by using a … [Read more...]

Memory modules have traditionally been available in two basic flavours: non-parity and parity. Parity checking uses a ninth memory chip to hold checksum data on the contents of the other eight chips in that memory bank. If the predicted value of … [Read more...]
